CTransInPlaceInputPin.CheckMediaType method

  • Article

[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

The CheckMediaType method determines if the pin accepts a specific media type.

Syntax

HRESULT CheckMediaType(
   const CMediaType *pmt
);

Parameters

pmt

Pointer to a CMediaType object that contains the proposed media type.

Return value

Returns S_OK if the proposed media type is acceptable. Otherwise, returns S_FALSE or an error code.

Remarks

This method overrides the CTransformInputPin::CheckMediaType method. It calls the filter's CTransformFilter::CheckInputType method to check the input type. If the output pin is connected, this method also calls the IPin::QueryAccept method on the downstream input pin.
